Using a CE Diagnostic Tool
You can use library diagnostic tools or third-party service tools to update
library and drive firmware from a laptop computer.
When using a narrow single-ended SCSI host adapter in the laptop,
additional equipment will typically be needed:
• A 50-pin to 68-pin adapter cable (ideally with high-byte termination).
If using the standard Adaptec PCMCIA to HD 50-pin male cable, the
adapter cable will need a HD 50-pin female end.
• A single-ended/HVDS converter box (if the library/drive is HVDS).
• A single-ended SCSI terminator (if the library/drive is LVDS).
NOTE An LVDS terminator cannot be used when connecting to a single-ended
Adaptec PCMCIA card because the dif sense line is not used on
PCMCIA SCSI cards..
• An HVDS terminator (if the library/drive is HVDS).
The general procedure for using a CE diagnostic tool is as follows:
1. If necessary, install the diagnostic tool and firmware files onto the
laptop.
2. Ensure that the library is not being accessed by the host system.
3. Ensure that the library is powered off.
4. Disconnect the device from the host system, noting the cabling and
termination.
5. Connect the laptop SCSI interface to the device, using the
appropriate equipment and appropriate termination at the device
end.
6. Power on the library. Wait for the library to complete the power-on
test and inventory check, and power on the laptop.
7. This step is for upgrading drive firmware only. If upgrading library
firmware, continue to step 8.
Ensure that the drive is online (green LED is on, and yellow LED is
off). If not, place it online through the front panel.
